Dalton Gardens residents weigh $8.1 million irrigation overhaul, costs

Dalton Gardens residents were told that keeping irrigation water flowing could come with a steep bill: under an $8.1 million overhaul plan, a homeowner with five acres could owe about $25,000.

About 60 people filled Dalton Gardens City Hall on Monday as the Dalton Irrigation District walked through the proposal for infrastructure built in the 1950s. District leaders framed the meeting as an educational session, but the numbers made the stakes clear for property owners who depend on the system for the neighborhood’s irrigated character and yard water.

The district said the planning effort began in 2023 with a water supply improvement study and a search for funding. The next major step is expected June 8, when the board is set to consider a preliminary resolution to create a local improvement district covering roughly 942 acres. Final approval could follow later in June. If that happens, the cost would fall largely on residents connected to the irrigation system.

District estimates put the expense at about $5,000 to $6,000 per acre. For a homeowner with five acres, that translates to roughly $25,000. Residents would be given a 30-day window to pay their share up front or repay it over time, but unpaid assessments could result in liens on homes tied to the irrigation network.

The district also said it has pursued three state grants. One has already been used to cover the study, while the other two could pay for about 35% of the project. The rest would be financed with a loan, adding another layer to the long-term cost of replacing and modernizing the system.

The debate reaches back more than a century. Bureau of Reclamation records show the Dalton Gardens Project was privately developed in the early 1900s, put into operation in 1905 and reorganized as an irrigation district in 1917. The system was rehabilitated in 1954-55 and again through pipe work in 1962-64. It serves about 980 acres on the Rathdrum Prairie, about two miles north of Coeur d’Alene.

The district’s own rules underscore how central the system remains to daily life in Dalton Gardens. Property owners are responsible for keeping mains and easements clear, and the district requires written approval for construction or planting within 20 feet on either side of irrigation mains.

The district office is at 6360 N. Fourth Street in Dalton Gardens, and board meetings are held at 6 p.m. on the second Monday of each month. As the June votes approach, residents are being asked to decide whether preserving irrigation service is worth absorbing a major new cost at the household level.
